Digital Companion for Field Drug Testing

Source

Source summary

Build a mobile/web companion to existing colour-reaction drug kits, with no new hardware. Capture the test beside a reference colour card for lighting correction, classify defined outcomes and create a tamper-evident signed record containing timestamp, GPS, operator ID and image hash. Provide a searchable test log. Outputs remain presumptive screening results with supporting records and do not replace laboratory confirmation.
